                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

As of December  31,  1999,  Century  Properties  Fund XX (the  "Partnership"  or
"Registrant") adopted the liquidation basis of accounting.

The  Partnership's  Nonrecourse  Promissory  Notes  (the  "Notes"),  which had a
balance of  principal  and  accrued  interest  of  approximately  $1,859,000  at
September  30, 2005,  matured on November 30, 1998.  The Notes bear  interest at
eight percent per annum.  The Partnership was in default due to non-payment upon
maturity.  Fox Capital Management  Corporation  ("FCMC" or the "Managing General
Partner")  previously  contacted the indenture trustee for the Notes and certain
holders  of  the  Notes  regarding  this  default.  On  October  28,  1999,  the
Partnership entered into a forbearance  agreement with the indenture trustee for
a period of 390 days.  In turn,  the  Partnership  agreed to (a)  deliver to the
indenture  trustee  for the benefit of the note  holders all of the  accumulated
cash  of the  Partnership,  less  certain  reserves  and  anticipated  operating
expenses,  (b) market  all of its  properties  for sale,  (c)  deliver  all cash
proceeds  from any  sales to the  indenture  trustee  until  the Notes are fully
satisfied and (d) comply with the reporting requirements under the indenture. At
the expiration of the  forbearance  period,  the Partnership had not sold all of
its  properties  or  satisfied  the Notes.  With the  consent  of the  indenture
trustee,  the forbearance  period was extended to December 15, 2001. The sale of
the  Partnership's  remaining asset in October 2001 did not generate  sufficient
proceeds to pay off the Notes in full. The Managing  General  Partner is working
with the debt trustee  regarding a final payment to the  noteholders.  Once this
payment is made, the Partnership is expected to terminate.  The Managing General
Partner  is  a  subsidiary  of  Apartment   Investment  and  Management  Company
("AIMCO"), a publicly traded real estate investment trust.

As a result of the  decision  to  liquidate  the  Partnership,  the  Partnership
changed its basis of  accounting  for its  financial  statements at December 31,
1999, to the  liquidation  basis of accounting.  Consequently,  assets have been
valued at estimated net realizable  value and liabilities are presented at their
estimated   settlement   amounts.   The  valuation  of  assets  and  liabilities
necessarily  requires many estimates and  assumptions  and there are substantial
uncertainties in carrying out the liquidation.  The actual realization of assets
and  settlement of liabilities  could be higher or lower than amounts  indicated
and is based upon the Managing General Partner's estimates as of the date of the
financial statements.

Included in liabilities in the statement of net liabilities in liquidation as of
September 30, 2005 is approximately  $121,000 of costs that the Managing General
Partner  estimates will be incurred  during the remaining  period of liquidation
based on the assumption that the liquidation  process will be completed by March
31, 2006. Because the settlement of liabilities is based on the Managing General
Partner's best estimates,  the liquidation  period may be shorter than projected
or it may be extended beyond the projected period.

Note B - Transactions with Affiliated Parties

The Partnership has no employees and depends on the Managing General Partner and
its  affiliates  for  the  management  and  administration  of  all  partnership
activities.   The  Partnership   Agreement  provides  for  certain  payments  to
affiliates for services and as  reimbursement  of certain  expenses  incurred by
affiliates on behalf of the Partnership.  No such reimbursements were charged or
paid during the nine months ended September 30, 2005 and 2004.

During the nine months ended  September  30, 2005,  an affiliate of the Managing
General Partner advanced the Partnership  approximately $45,000 to pay operating
expenses.  No interest was charged on this advance.  At September 30, 2005,  the
Partnership owed approximately $85,000 for advances from affiliates.

Note C - Contingencies

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purported  to  assert  claims  on  behalf  of a class of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  that are named as nominal  defendants,  challenging,  among  other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc.  ("Insignia") and entities that were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged into AIMCO.  The plaintiffs  sought  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
In addition,  during the third quarter of 2001, a complaint  captioned Heller v.
Insignia  Financial  Group (the  "Heller  action")  was filed  against  the same
defendants  that are named in the  Nuanes  action.  On or about  August 6, 2001,
plaintiffs filed a first amended  complaint.  The Heller action was brought as a
purported derivative action, and asserted claims for, among other things, breach
of fiduciary  duty,  unfair  competition,  conversion,  unjust  enrichment,  and
judicial  dissolution.  On January 28, 2002, the trial court granted  defendants
motion to strike the complaint. Plaintiffs took an appeal from this order.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement of the Nuanes  action and the Heller  action.  On June 13, 2003,  the
court granted final approval of the settlement and entered  judgment in both the
Nuanes and Heller actions. On August 12, 2003, an objector ("Objector") filed an
appeal (the "Appeal")  seeking to vacate and/or reverse the order  approving the
settlement and entering judgment  thereto.  On May 4, 2004, the Objector filed a
second appeal  challenging  the court's use of a referee and its order requiring
Objector to pay those fees.

On March 21, 2005, the Court of Appeals issued opinions in both pending appeals.
With regard to the settlement and judgment entered thereto, the Court of Appeals
vacated  the trial  court's  order and  remanded  to the trial court for further
findings  on the basis that the "state of the record is  insufficient  to permit
meaningful  appellate  review".  With regard to the second appeal,  the Court of
Appeals  reversed the order requiring the Objector to pay referee fees. On April
26, 2005,  the Court of Appeals  lifted the stay of a pending  appeal related to
the Heller action and the trial court's order striking the  complaint.  On April
28, 2005, the Objector  filed a Petition for Review with the California  Supreme
Court in connection with the opinion vacating the order approving settlement and
remanding for further findings.  On June 10, 2005, the California  Supreme Court
denied  Objector's  Petition for Review and the Court of Appeals sent the matter
back to the trial court on June 21,  2005.  The parties  intend to ask the trial
court to make further findings in connection with settlement consistent with the
Court of Appeal's  remand order.  With respect to the related Heller appeal,  on
July 28, 2005,  the Court of Appeals  reversed the trial court's order  striking
the first amended complaint.

On August 18, 2005,  Objector and his counsel filed a motion to  disqualify  the
trial court based on a peremptory challenge and filed a motion to disqualify for
cause on October 17, 2005. On or about October 13, 2005 Objector  filed a motion
to  intervene  and on or about  October  19,  2005  filed  both a motion to take
discovery  relating to the adequacy of plaintiffs as derivative  representatives
and a motion to dissolve the anti-suit injunction in connection with settlement.
On October 27, 2005, the Court denied Objector's peremptory challenge and struck
Objector's motion to disqualify for cause. No hearing has been set on Objector's
remaining motions. On November 3, 2005, Objector and his counsel filed a writ of
mandate to the Court of Appeals challenging the court's October 27, 2005 order.

The  Managing  General  Partner  does  not  anticipate  that  any  costs  to the
Partnership,  whether legal or settlement costs,  associated with this case will
be material to the Partnership's overall operations.

On August 17, 2004, the  Partnership was sued,  along with the Managing  General
Partner, Fox Capital Management  Corporation,  and general partner, Fox Partners
III.  The suit was  brought in the Supreme  Court of the State of New York,  New
York County by J.P.  Morgan Trust  Company,  N.A.,  ("Trustee")  formerly  Chase
Manhattan Bank & Trust Company, N.A., as Trustee under the Trust Indenture dated
as of February 22, 1984.  The Trustee  alleges  claims of breach of contract and
unjust  enrichment based on defendants'  alleged  breaches of their  obligations
under a Forbearance  Agreement  dated as of October 28, 1999.  The Trustee seeks
the  payment of certain  funds that it  contends  were  improperly  withheld  or
misappropriated  under the  Forbearance  Agreement.  In its  breach of  contract
claim,  the Trustee claims that it is entitled to $541,776 plus interest,  which
is  comprised  of  management  fees  paid to Fox  Partners  III and  outstanding
reserves  allegedly  due to the  Trustee.  The parties  have reached a tentative
settlement  agreement  wherein  all the  defendants  will pay  $700,000  for the
settlement  of  this  case  as  well as an  additional  case  involving  Century
Properties Fund XXIII,  an affiliate.  The allocation on how those funds will be
divided between the defendants is yet to be determined. The tentative settlement
agreement is in the process of being finalized and documented.

SEC Investigation

The  Central  Regional  Office of the  United  States  Securities  and  Exchange
Commission (the "SEC")  continues its formal  investigation  relating to certain
matters.  Although  the staff of the SEC is not limited in the areas that it may
investigate,  AIMCO believes the areas of  investigation  have included  AIMCO's
miscalculated   monthly  net  rental  income  figures  in  third  quarter  2003,
forecasted  guidance,  accounts  payable,  rent  concessions,   vendor  rebates,
capitalization of payroll and certain other costs, tax credit transactions,  and
tender offers for limited  partnership  interests.  AIMCO is cooperating  fully.
AIMCO is not able to predict when the investigation will be resolved. AIMCO does
not believe that the ultimate outcome will have a material adverse effect on its
consolidated  financial  condition  or results  of  operations.  Similarly,  the
Managing  General Partner does not believe that the ultimate outcome will have a
material adverse effect on the Partnership's  financial  condition or results of
operations.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATIONS

The matters discussed in this report contain certain forward-looking statements,
including, without limitation, statements regarding future financial performance
and the effect of government  regulations.  Actual results may differ materially
from those described in the forward-looking statements and will be affected by a
variety of risks and factors including,  without limitation:  national and local
economic  conditions;  the terms of  governmental  regulations  that  affect the
Registrant and interpretations of those regulations; litigation, including costs
associated  with  prosecuting  and  defending  claims and any adverse  outcomes.
Readers should carefully review the  Registrant's  financial  statements and the
notes  thereto,  as well as the risk  factors  described  in the  documents  the
Registrant files from time to time with the Securities and Exchange Commission.

As of December  31,  1999,  Century  Properties  Fund XX (the  "Partnership"  or
"Registrant")  adopted the liquidation  basis of accounting.  The  Partnership's
Nonrecourse Promissory Notes (the "Notes"), which had a balance of principal and
accrued interest of approximately  $1,859,000 at September 30, 2005,  matured on
November  30,  1998.  The notes bear  interest at eight  percent per annum.  The
Partnership  was in  default  due to  non-payment  upon  maturity.  Fox  Capital
Management  Corporation  ("FCMC" or the "Managing General  Partner")  previously
contacted the indenture  trustee for the Notes and certain  holders of the Notes
regarding  this default.  On October 28, 1999,  the  Partnership  entered into a
forbearance  agreement  with the indenture  trustee for a period of 390 days. In
turn,  the  Partnership  agreed to (a) deliver to the indenture  trustee for the
benefit of the note holders all of the accumulated cash of the Partnership, less
certain  reserves  and  anticipated  operating  expenses,  (b) market all of its
properties  for  sale,  (c)  deliver  all cash  proceeds  from any  sales to the
indenture  trustee  until the Notes are fully  satisfied and (d) comply with the
reporting requirements under the indenture. At the expiration of the forbearance
period,  the  Partnership  had not sold all of its  properties  or satisfied the
Notes.  With the consent of the indenture  trustee,  the forbearance  period was
extended to December 15, 2001. The sale of the Partnership's  remaining asset in
October 2001 did not generate  sufficient proceeds to pay off the Notes in full.
The Managing General Partner is working with the debt trustee  regarding a final
payment to the  noteholders.  Once this  payment  is made,  the  Partnership  is
expected to terminate.

As a result of the  decision  to  liquidate  the  Partnership,  the  Partnership
changed its basis of  accounting  for its  financial  statements at December 31,
1999 to the  liquidation  basis of  accounting.  Consequently,  assets have been
valued at estimated net realizable  value and liabilities are presented at their
estimated   settlement   amounts.   The  valuation  of  assets  and  liabilities
necessarily  requires many estimates and  assumptions  and there are substantial
uncertainties in carrying out the liquidation.  The actual realization of assets
and  settlement of liabilities  could be higher or lower than amounts  indicated
and is based upon the Managing General Partner's estimates as of the date of the
financial statements.

During the nine months ended  September 30, 2005, net liabilities in liquidation
increased  by  approximately  $112,000.  The increase is due to increases in the
accrued interest payable on the Notes, due to affiliates, other liabilities, and
to a decrease in the debt trustee escrow  partially  offset by a decrease in the
estimated costs during the period of liquidation. The estimated costs during the
period of  liquidation  decreased due to the change in the period of liquidation
partially  offset  by an  increase  in the  expected  legal  and  administrative
expenses.

During the nine months ended  September 30, 2004, net liabilities in liquidation
increased  by  approximately  $277,000.  The increase is due to increases in the
accrued  interest  payable on the Notes,  due to affiliates and in the estimated
costs  during the period of  liquidation,  and to a decrease in the debt trustee
escrow, partially offset by a decrease in other liabilities. The estimated costs
during the period of  liquidation  increased  due to an increase in the expected
legal and administrative  expenses and an increase in the expected time required
to liquidate the Partnership.

Included in the statement of net  liabilities in liquidation as of September 30,
2005 is  approximately  $121,000  of costs  that the  Managing  General  Partner
estimates  will be  incurred  during  the  period  of  liquidation  based on the
assumption  that the  liquidation  process  will be completed by March 31, 2006.
Because the settlement of liabilities is based on the Managing General Partner's
best estimates,  the liquidation  period may be shorter than projected or it may
be extended beyond the projected period.

In light of the maturity of the Notes, no distributions were made to the limited
partners for the nine months ended September 30, 2005 and 2004.

In addition to its indirect  ownership of the Managing  General Partner interest
in the  Partnership,  AIMCO and its affiliates  owned 3,950 limited  partnership
units  in the  Partnership  representing  6.39%  of  the  outstanding  units  at
September  30,  2005.  AIMCO  and its  affiliates  also own  8,977 of the  notes
representing 9.10% of the outstanding notes at September 30, 2005.

ITEM 3.     CONTROLS AND PROCEDURES

(a) Disclosure Controls and Procedures.  The Partnership's management,  with the
participation of the principal executive officer and principal financial officer
of the Managing  General  Partner,  who are the equivalent of the  Partnership's
principal executive officer and principal financial officer,  respectively,  has
evaluated  the  effectiveness  of  the  Partnership's  disclosure  controls  and
procedures (as such term is defined in Rules  13a-15(e) and 15d-15(e)  under the
Securities  Exchange Act of 1934, as amended (the "Exchange Act")) as of the end
of the period covered by this report.  Based on such  evaluation,  the principal
executive  officer  and  principal  financial  officer of the  Managing  General
Partner, who are the equivalent of the Partnership's principal executive officer
and principal  financial officer,  respectively,  have concluded that, as of the
end of such period,  the  Partnership's  disclosure  controls and procedures are
effective.

(b) Internal Control Over Financial  Reporting.  There have not been any changes
in the Partnership's  internal control over financial reporting (as such term is
defined in Rules  13a-15(f)  and  15d-15(f)  under the Exchange  Act) during the
fiscal quarter to which this report relates that have  materially  affected,  or
are reasonably likely to materially affect,  the Partnership's  internal control
over financial reporting.

                           PART II - OTHER INFORMATION


ITEM 1.     LEGAL PROCEEDINGS

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purported  to  assert  claims  on  behalf  of a class of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  that are named as nominal  defendants,  challenging,  among  other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc.  ("Insignia") and entities that were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged into AIMCO.  The plaintiffs  sought  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
In addition,  during the third quarter of 2001, a complaint  captioned Heller v.
Insignia  Financial  Group (the  "Heller  action")  was filed  against  the same
defendants  that are named in the  Nuanes  action.  On or about  August 6, 2001,
plaintiffs filed a first amended  complaint.  The Heller action was brought as a
purported derivative action, and asserted claims for, among other things, breach
of fiduciary  duty,  unfair  competition,  conversion,  unjust  enrichment,  and
judicial  dissolution.  On January 28, 2002, the trial court granted  defendants
motion to strike the complaint. Plaintiffs took an appeal from this order.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement of the Nuanes  action and the Heller  action.  On June 13, 2003,  the
court granted final approval of the settlement and entered  judgment in both the
Nuanes and Heller actions. On August 12, 2003, an objector ("Objector") filed an
appeal (the "Appeal")  seeking to vacate and/or reverse the order  approving the
settlement and entering judgment  thereto.  On May 4, 2004, the Objector filed a
second appeal  challenging  the court's use of a referee and its order requiring
Objector to pay those fees.

On March 21, 2005, the Court of Appeals issued opinions in both pending appeals.
With regard to the settlement and judgment entered thereto, the Court of Appeals
vacated  the trial  court's  order and  remanded  to the trial court for further
findings  on the basis that the "state of the record is  insufficient  to permit
meaningful  appellate  review".  With regard to the second appeal,  the Court of
Appeals  reversed the order requiring the Objector to pay referee fees. On April
26, 2005,  the Court of Appeals  lifted the stay of a pending  appeal related to
the Heller action and the trial court's order striking the  complaint.  On April
28, 2005, the Objector  filed a Petition for Review with the California  Supreme
Court in connection with the opinion vacating the order approving settlement and
remanding for further findings.  On June 10, 2005, the California  Supreme Court
denied  Objector's  Petition for Review and the Court of Appeals sent the matter
back to the trial court on June 21,  2005.  The parties  intend to ask the trial
court to make further findings in connection with settlement consistent with the
Court of Appeal's  remand order.  With respect to the related Heller appeal,  on
July 28, 2005,  the Court of Appeals  reversed the trial court's order  striking
the first amended complaint.

On August 18, 2005,  Objector and his counsel filed a motion to  disqualify  the
trial court based on a peremptory challenge and filed a motion to disqualify for
cause on October 17, 2005. On or about October 13, 2005 Objector  filed a motion
to  intervene  and on or about  October  19,  2005  filed  both a motion to take
discovery  relating to the adequacy of plaintiffs as derivative  representatives
and a motion to dissolve the anti-suit injunction in connection with settlement.
On October 27, 2005, the Court denied Objector's peremptory challenge and struck
Objector's motion to disqualify for cause. No hearing has been set on Objector's
remaining motions. On November 3, 2005, Objector and his counsel filed a writ of
mandate to the Court of Appeals challenging the court's October 27, 2005 order.

The  Managing  General  Partner  does  not  anticipate  that  any  costs  to the
Partnership,  whether legal or settlement costs,  associated with this case will
be material to the Partnership's overall operations.

On August 17, 2004, the  Partnership was sued,  along with the Managing  General
Partner, Fox Capital Management  Corporation,  and general partner, Fox Partners
III.  The suit was  brought in the Supreme  Court of the State of New York,  New
York County by J.P.  Morgan Trust  Company,  N.A.,  ("Trustee")  formerly  Chase
Manhattan Bank & Trust Company, N.A., as Trustee under the Trust Indenture dated
as of February 22, 1984.  The Trustee  alleges  claims of breach of contract and
unjust  enrichment based on defendants'  alleged  breaches of their  obligations
under a Forbearance  Agreement  dated as of October 28, 1999.  The Trustee seeks
the  payment of certain  funds that it  contends  were  improperly  withheld  or
misappropriated  under the  Forbearance  Agreement.  In its  breach of  contract
claim,  the Trustee claims that it is entitled to $541,776 plus interest,  which
is  comprised  of  management  fees  paid to Fox  Partners  III and  outstanding
reserves  allegedly  due to the  Trustee.  The parties  have reached a tentative
settlement  agreement  wherein  all the  defendants  will pay  $700,000  for the
settlement  of  this  case  as  well as an  additional  case  involving  Century
Properties Fund XXIII,  an affiliate.  The allocation on how those funds will be
divided between the defendants is yet to be determined. The tentative settlement
agreement is in the process of being finalized and documented.
